Krea details Seedance 2.5's reference limits
Krea has published the API limits for ByteDance's Seedance 2.5, including 50 multimodal references and clips up to 30 seconds, and says builders must trade these for lower native resolution than Seedance 2.0.
As we reported earlier, Krea added ByteDance's Seedance 2.5 video model to its platform. Krea has now published a guide that lists the model's limits on its API.
A single request can include up to 30 reference images, 10 reference videos and 10 reference audio clips, for 50 multimodal references in total. Clips run from 4 to 30 seconds. Native output is limited to 480p and 720p. The model supports six aspect ratios, one start image and one end image, an integer seed for reproducible results, and up to 12 named effects. Prompt is the only required field. An optional generate_audio flag, off by default, creates a soundtrack in the same pass as the video. Krea's model page also lists an extended beta mode that can reach 180 seconds, along with region-level editing that fixes a face, object or background without regenerating the whole clip.
Krea frames the choice between versions as a trade-off. Seedance 2.0 on Krea accepts 15 references and clips of 4 to 15 seconds, but it outputs native 1080p and 4K and can upscale to 8K. Krea recommends 2.5 when a project needs continuity across many inputs or longer clips, and 2.0 when it needs high-resolution delivery.
The guide cites a reported improvement of roughly 20% in prompt adherence. In Krea's own tests, a text-only prompt still produced the wrong character and setting. The company advises supplying a separate reference for each face, product and location that has to stay consistent.
